Stock and the Purchase Price are subject to adjustment as provided herein.

         The purchase price per share of Common Stock issuable upon exercise of
this Warrant (the "PURCHASE PRICE") shall initially be $0.26, PROVIDED, HOWEVER,
that the Purchase Price shall be adjusted from time to time as provided herein.

(however designated) of the Company, authorized on or after such date, the
holders of which shall have the right, without limitation as to amount, either
to all or to a share of the balance of current dividends and liquidating
dividends after the payment of dividends and distributions on any shares
entitled to preference, and the holders of which shall ordinarily, in the
absence of contingencies, be entitled to vote for the election of a majority of
directors of the Company (even though the right so to vote has been suspended by
the happening of such a contingency) and (c) any other securities into which or
for which any of the securities described in (a) or (b) may be converted or
exchanged pursuant to a plan of recapitalization, reorganization, merger, sale

<PAGE>

         (c) The term "OTHER SECURITIES" refers to any stock (other than Common
Stock) and other securities of the Company or any other person (corporate or
otherwise) that the Holder of this Warrant at any time shall be entitled to
receive, or shall have received, on the exercise of this Warrant, in lieu of or
in addition to Common Stock, or that at any time shall be issuable or shall have
been issued in exchange for or in replacement of Common Stock or Other

2.       EXERCISE OF WARRANT.

                  2.1      METHOD OF EXERCISE.

                  (a) This warrant may be exercised in whole or in part (but not
as to a fractional share of Common Stock), at any time and from time to time
during the Exercise Period by the Holder hereof by delivery of a notice of
exercise (a "NOTICE OF EXERCISE") substantially in the form attached hereto as
Exhibit A via facsimile to the Company. Promptly thereafter the Holder shall
surrender this Warrant to the Company at its principal office, accompanied by
payment of the Purchase Price multiplied by the number of shares of Common Stock
for which this Warrant is being exercised (the "EXERCISE PRICE"). Payment of the
Exercise Price shall be made, at the option of the Holder, (i) by check or bank
draft payable to the order of the Company, or (ii) by wire transfer to the
account of the Company.

                  (b) In addition to the foregoing, at the option of Holder,
this Warrant may be exercised, at any time or from time to time, in the
following "cashless exercise" transactions:

                  (i) Upon written notice of exercise from the Holder to the
         Company that the Holder is exercising this Warrant in whole or in part
         and as consideration of such exercise is authorizing the Company to
         withhold from issuance a number of shares of Common Stock issuable upon
         exercise of this Warrant, the Company shall deliver to the Holder
         (without payment by the Holder of the aggregate Purchase Price) that
         number of shares of Common Stock equal to the quotient obtained by
         dividing (x) the Spread Value by (y) the Fair Market Value of one share
         of Common Stock immediately prior to the exercise of the Conversion
         Right. The shares withheld by the Company shall no longer be issuable
         under this Warrant.

                  (ii) Fair Market Value of a share of Warrant Shares as of a
         particular date (the "Determination Date") shall mean:

                           (A) If the Warrant Shares are traded on an exchange
                  or are quoted on the Nasdaq National Market or the Nasdaq
                  SmallCap Market ("Nasdaq"), then the average of the closing or
                  last sale price, respectively, reported for the five trading
                  days immediately preceding the Determination Date.

                           (B) If the Warrant Shares are not traded on an
                  exchange or on Nasdaq but are traded in the over-the-counter
                  market or other similar organization (including the OTC
                  Bulletin Board), then the average of the closing bid and ask
                  prices reported for the five trading days immediately
                  preceding the Determination Date.

                           (C) If the Warrant Shares are not traded as provided
                  above, then the price determined in good faith by the Board of
                  Directors of the Company, provided that (i) the basis or bases
                  of each such determination shall be set forth in the corporate
                  records of the Company pertaining to meetings and other
                  actions of such board, and (ii) such records are available to
                  the Holder for inspection during normal business hours of the
                  Company upon the giving of reasonable prior notice.

                           (D) If the Determination Date is the date of a
                  liquidation, dissolution or winding up, or any event deemed to
                  be a liquidation, dissolution or winding up pursuant to the
                  Company's certificate of incorporation, then all amounts to be
                  payable per share to Holders of the securities then comprising
                  Warrant Shares pursuant to the charter in the event of such
                  liquidation, dissolution or winding up, plus all other amounts
                  to be payable per share in respect of the Warrant Shares in
                  liquidation under the certificate of incorporation, assuming
                  for the purposes of this clause (D) that all of the shares of
                  Warrant Shares then issuable upon exercise of all of the
                  Warrants are outstanding at the Determination Date.

                                       2
<PAGE>

                  (iii) The term "Spread Value" shall mean (i) the number of
         shares exercised at a given time multiplied by the Fair Market Value of
         one share of Common Stock, less (ii) aggregate applicable Exercise
         Price.

                  (c) Upon exercise, the Holder shall be entitled to receive,
promptly after payment in full, one or more certificates, issued in the Holder's
name or in such name or names as the Holder may direct, subject to the
limitations on transfer contained herein, for the number of shares of Common
Stock so purchased. The shares of Common Stock so purchased shall be deemed to
be issued as of the close of business on the date on which the Company shall
have received from the Holder payment in full of the Exercise Price (the
"EXERCISE DATE").

                  (d) Notwithstanding anything to the contrary set forth herein,
upon exercise of all or a portion of this Warrant in accordance with the terms
hereof, the Holder shall not be required to physically surrender this Warrant to
the Company. Rather, records showing the amount so exercised and the date of
exercise shall be maintained on a ledger substantially in the form of Annex B
attached hereto (a copy of which shall be delivered to the Company or transfer
agent with each Notice of Exercise). It is specifically contemplated that the
Holder hereof shall act as the calculation agent for all exercises of this
Warrant. In the event of any dispute or discrepancies, such records maintained
by the Holders shall be controlling and determinative in the absence of manifest
error. The Holder and any assignee, by acceptance of this Warrant, acknowledge
and agree that, by reason of the provisions of this paragraph, following an
exercise of a portion of this Warrant, the number of shares of Common Stock
represented by this Warrant will be the amount indicated on Annex B attached
hereto (which may be less than the amount stated on the face hereof)."

                  2.2 REGULATION D RESTRICTIONS. The Holder hereof represents
and warrants to the Company that it has acquired this Warrant and anticipates
acquiring the shares of Common Stock issuable upon exercise of the Warrant
solely for its own account for investment purposes and not with a view to or for
resale of such securities unless such resale has been registered with the
Commission or an applicable exemption is available therefore. At the time this
Warrant is exercised, the Company may require the Holder to state in the Notice
of Exercise such representations concerning the Holder as are necessary or
appropriate to assure compliance by the Holder with the Securities Act.

                  2.3 COMPANY ACKNOWLEDGMENT. The Company will, at the time of
the exercise of this Warrant, upon request of the Holder hereof, acknowledge in
writing its continuing obligation to afford to such Holder the registration
rights to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of a Registration Rights Agreement dated the date
hereof (the "Registration Rights Agreement"). If the Holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford such Holder any such rights.

                  2.4 LIMITATION ON EXERCISE. Notwithstanding the rights of the
Holder to exercise all or a portion of this Warrant as described herein, such
exercise rights shall be limited, solely to the extent set forth in the Purchase
Agreement as if such provisions were specifically set forth herein. In addition,
the number of shares of Common Stock issuable upon exercise of this Warrant is
subject to reduction as specified in Section 10.3 of the Purchase Agreement.

         3. DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. As soon as
practicable after the exercise of this Warrant, and in any event within three
(3) business days thereafter, the Company at its expense (including the payment
by it of any applicable issue, stamp or transfer taxes) will cause to be issued
in the name of and delivered to the Holder thereof, or, to the extent
permissible hereunder, to such other person as such Holder may direct, a
certificate or certificates for the number of fully paid and nonassessable
shares of Common Stock (or Other Securities) to which such Holder shall be
entitled on such exercise, plus, in lieu of any fractional share to which such
Holder would otherwise be entitled, cash equal to such fraction multiplied by
the then applicable Purchase Price, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 2 or otherwise.

                                       3
<PAGE>

         4. ADJUSTMENT FOR EXTRAORDINARY EVENTS. The Purchase Price to be paid
by the Holder upon exercise of this Warrant, and the consideration to be
received upon exercise of this Warrant, shall be adjusted in case at any time or
from time to time pursuant to Article XI of the Purchase Agreement as if such
provisions were specifically set forth herein.

         5. NO IMPAIRMENT. The Company will not, by amendment of its Certificate
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder of this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock
receivable on the exercise of this Warrant above the amount payable therefor on
such exercise, (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
unassessable shares of stock on the exercise of this Warrant, and (c) will not
transfer all or substantially all of its properties and assets to any other
person (corporate or otherwise), or consolidate with or merge into any other
person or permit any such person to consolidate with or merge into the Company
(if the Company is not the surviving person), unless such other person shall
expressly assume in writing and will be bound by all the terms of this Warrant.

         6. ACCOUNTANT'S CERTIFICATE AS TO ADJUSTMENTS. In each case of any
adjustment or readjustment in the shares of Common Stock (or Other Securities)
issuable on the exercise of this Warrant, the Company at its expense will
promptly cause independent certified public accountants of national standing
selected by the Company to compute such adjustment or readjustment in accordance
with the terms of this Warrant and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (a) the
consideration received or receivable by the Company for any additional shares of
Common Stock (or Other Securities) issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock (or Other Securities)
outstanding or deemed to be outstanding, and (c) the Purchase Price and the
number of shares of Common Stock to be received upon exercise of this Warrant,
in effect immediately prior to such issue or sale and as adjusted and readjusted
as provided in this Warrant. The Company will forthwith mail a copy of each such
certificate to the Holder of this Warrant, and will, on the written request at
any time of the Holder of this Warrant, furnish to such Holder a like
certificate setting forth the Purchase Price at the time in effect and showing
how it was calculated.

         7. NOTICES OF RECORD DATE, ETC. In the event of

                  (a) any taking by the Company of a record of the holders of
any class or securities for the purpose of determining the holders thereof who
are entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

                  (b) any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
transfer of all or substantially all the assets of the Company to or
consolidation or merger of the Company with or into any other person, or

                  (c) any voluntary or involuntary dissolution, liquidation or
winding- up of the Company,

then and in each such event the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, and
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any, as of which the holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or Other Securities) for then and in each such event the
Company will mail or cause to be mailed to the Holder of this Warrant a notice
specifying (i) the date on which any such record is to be taken for the purpose


                                       4

dissolution, liquidation or winding-up. Such notice shall be mailed at least 20
days prior to the date specified in such notice on which any action is to be
taken.

         8. RESERVATION OF STOCK, ETC. ISSUABLE ON EXERCISE OF WARRANT. The
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise of this Warrant, all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of this Warrant.

will issue and deliver to or on the order of the Holder thereof a new Warrant of

mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.
